Chapter_56_Heartbeat

Second day on the grid; same sheet, same work.

The two night shifts walked, eight spools counted. The city's lamps stood dark for a third night, and the morning talk in the wards ran short—people slept early, rose early, and the light they saved went down that line into the ground a little at a time. Under the dark half of the lane-mouth lamp posts, something new hung: lamps the households had given up, not taken down, but wrapped in cloth and hung back in place. By day a post of shrouded lamps read like a ledger—who had given, marked where they lived.

Xiao Mao opened his book first thing and copied the night's entry clean: time of the switch, first gun's self-check, the shaft wind turning. At the wind line he paused, then drew a rule across the blank half page he'd left. A number with no head—give it a head first.

Big Liu leaned over, said nothing, and folded the corner of his own switch ledger. The wind hour was in his book too. Two books, one hour.

The morning's work was stake measuring. Eight stakes, every count square, the earth at the bases tamped two days back, no fresh shift. The lamp posts around the circle had given up their lamps two nights ago, and the crews had stopped missing them—dark posts, bright rope, one count to each. He reported the numbers as always. Chen Jin listened, drew the sheet halfway out of his sleeve, looked at the changed header—works, grid connection into the sinkhole—the small note unchanged, and put it back.

"Into the tunnel."

"The stakes?" Big Liu asked.

"The self-checked gun."

Eight lamps lit and checked; down. Fifth trip on that road—fifteen steps, the door cups, the call three times—and the feet knew it so well the talk fell away. Who walked where needed no arranging: the old mason last, Big Liu on the lamp, Xiao Mao on the inner side, habit walking the men into place. The passage brass handed light into the hall, and they followed it, footsteps going into the stone a bite at a time.

The first cradle on the east rank. The one fed yesterday.

Oil-cloth still folded at the foot, mouth to the sky, straight at the shaft. The old mason's hand went out first, palm to the barrel, one breath, back.

"Warm."

"It was warm yesterday," Xiao Mao said.

"Yesterday's warmth sat in the palm." He pressed again, three times, palm flat, lift, palm. "Today it's at the wrist. Something in there is moving, and moving even."

Big Liu tried it, half a breath, and pulled his hand off. "Wrong kind of warm. A dead thing's warmth spreads. This gathers—runs one line, base to mouth."

"Power in the line," Xiao Mao said.

"Power passes through," the old mason said. "This warmth has moved in."

A gun fed once was like a man fed once: a fed hand is a living hand. Nobody said it. All four tried the palm anyway, one after another, and nobody said it.

Xiao Mao laid his book open to enter the self-check line against the cradle. The nib had just touched down—

Under the ground, one stroke.

Not from the gun. The barrel didn't move; the cradle didn't move; Xiao Mao's nib hung in the air. It came from deeper—through the floor, through layers of stone past counting—up: one stroke, heavy, slow, like somewhere very far off a man setting down something very heavy, once, with care.

All four stood still. Big Liu's hand was still on the barrel; the stroke passed under his palm. Xiao Mao's nib touched paper and spread one blot.

The second stroke took a long time coming. Then a third. One stroke, another, the interval even as something measured.

The hall ate sound. This sound it didn't eat—it didn't come by the ears, it came by the ground, up the bones of the legs. Nobody spoke. Bug sound is broken; water sound is scattered; this was one stroke to a stroke, solid. No hurry in it, no push, one stroke and one stroke—like something far below that had stopped sleeping soundly, turned over, gone on sleeping, and was counting in its sleep.

The old mason put his ear to the barrel. Three breaths, then up, a shake of the head at Chen Jin—not in the gun. Chen Jin was already down, palm flat to the floor. Big Liu followed. Three hands on the stone, the rhythm passing under them, stroke and stroke.

"It travels down there," Big Liu said, voice dropped. "Not on our level."

The tale has been illicitly lifted; should you spot it on Amazon, report the violation.

"Deeper than us," the old mason said. "Far."

Xiao Mao crouched too, but his eyes weren't on the floor—they were on the seams. Dust lay in the old floor seams, and with each stroke the dust jumped, fine as anything, invisible unless you looked. Four seams, four directions, and every seam's dust jumped one way: slantwise, toward the line that ran to the west wall.

"The dust knows the road," he said, barely above breath.

Fine as the jumping was, not one seam jumped false. West wall—dial, line, cradle base—the road they'd fed yesterday. Whether the dust followed the line or whatever lay under the line, nobody could say. The old mason watched two full rhythms, pinched a grain of dust from the nearest seam, rolled it on his fingertip, held it to the lamp.

"Dead dust," he said. "The jumping isn't the dust."

Chen Jin lowered his lamp.

The flame crouched; the black closed a ring closer. He wanted to see the stroke-and-stroke clearly—look hard before you touch, the old rule, his rule.

The lamp went low, and—

The rhythm missed a beat.

The stroke that should have come didn't. In the black, one breath of stillness, four men gathering their own breaths in. Then the next stroke fell, heavier than before, deeper by half—not nearer; the thing on the other end had raised its head, and turned an ear toward the lamp.

Chen Jin raised the lamp back.

The flame stood; the black gave ground. The next stroke fell as before, and the next. The interval came back—but wrong. He counted two full rounds to be sure: the gap ran shorter than before the lamp went low. Shorter by a hair, nothing you'd catch without counting. The thing down there had taken note of the lamp, and moved a half-step quicker.

"Shouldn't have lowered the lamp."

The words were no sooner out than he was sorry for them. He'd lowered the lamp to see clearly, and seeing clearly was for leaving things alone—and the lamp went low and startled it first. Rules are made by men, and the man making them doesn't reckon where the rule will land. It had slept past counting, and one lamp of his had cut its sleep a notch.

He ran those few breaths through again: the flame down, the black closing, and on the far side one beat held. Not fear—fear doesn't stop first and listen after. It heard, stopped to hear, and listened. That kind of listening sat heavier than the night the bugs went flat: the bugs had been beaten quiet. This was awake on its own.

"We've startled what's down there," he said, leveling it out for the three of them. "One rule changes: lamps don't go low. It listens to lamps—let it listen."

The old mason nodded once and thumbed the wick half a notch higher. The flame stood firm, and stayed.

The panel lit—on its own, not by his hand:

[Low-frequency rhythmic signal detected. Source: below.]

[Not insect-kind.]

[Not in register.]

Three lines, each shorter than the last. Big Liu leaned in, read, and asked: "Not in register—the books never wrote it down?"

"The register has no page for it," Chen Jin said.

"Two days we've been booking things—guns, line, socket, all in," Big Liu said, reading the lines again. "It's under our feet and there's no page?"

Chen Jin didn't answer. What could be entered had a source, a count, a name. Under these three lines the system offered no name, no count, no origin—a register however full has edges, and here was past the edge of it.

The old mason raised his lamp and took the hall around slowly—two ranks of cradles, twenty-four shafts, the dial on the west wall—his eyes resting on each, and coming back down to his own feet.

"The guns sleep," he said. "The thing below sleeps. Yesterday we closed a switch and fed the guns—and it ate a mouthful too, through a few floors of stone."

Nobody picked that up. There was nothing to pick up. The rhythm went on under their feet, stroke and stroke, half a step quicker than before.

"Let's go," Chen Jin said. "Stop standing around its sleep."

They came up with the sun still high. Eight lamps, not one short.

After dusk, the watch at the circle mouth heard it first.

The sound had come up through the ground. Down there by day it traveled by the soles; at night on the surface it seeped up through the earth into the knees of the men in the shadows. The watch changed, and both men on it had heard; they reported it in their own words at handover: movement under the ground, stroke and stroke, not bug, not water. Neither man had gone toward it. Both had stayed where they were posted and listened, which was the report that mattered.

"Not bug—then what?"

"Don't know." The man worked his knee with his palm. "Only it sounds like something under there has drawn breath."

Big Liu had it written down word for word, no touching. When the man had gone he stared a while at the black of the sinkhole. "Heard from below by day, heard from the surface by night," he said. "One day, and its reach grew a full ring."

"Either it's grown stronger," Chen Jin said, "or the power we fed it has—and there's no telling which. Night watch goes to three shifts. The wall roster stands."

"And lamps?"

"No more lamps." Chen Jin said. "Walk it dark. It listens for lamps."

Wen Heng heard it from the shed. She didn't come out to look; she set her ear to the door plank for three breaths, then entered it in the little book: ground-sound, stroke and stroke, from nightfall. The pen paused, and she added four words: heavier than by day.

In the shop, Big Liu finished the switch ledger and said the heartbeat's hours wanted recording too. Xiao Mao's book was already open. Two pens, two books, one page of accounts and one page of strokes, each keeping his own, neither in the other's way.

One stroke, one line. One stroke, one line. The nib walked with the sound; the sound was slow, and the lines fell slow. The blank half page filled toward its end, line under line, even.

Counting, the pen stopped.

The next line that should have fallen didn't. The sound had stopped.

Xiao Mao's nib hung over the paper a long time. The dark came down quieter than quiet—before, the stillness had a rhythm holding it up; now even the thing holding it up had been drawn away. Across the shop Big Liu's pen stopped too: two books, one behind the other, stopped at the same place.

He didn't dare lift his eyes to anyone's face. At the tail of the last unfinished line he set one small dot. Before closing the book he counted the filled page through: forty-nine lines.

Past the fortieth, the lines ran closer than the first. Whatever was quickening down there was not the only thing counting faster.

Chen Jin brought the panel up, and put it away without asking. Dark was dark; sleeping things slept. But he knew the page would go on filling tomorrow.
